Friend being racist

Soo to be clear I’m really friendly to all kinds 🤷🏽‍♀️ that’s just my personality. Well today i met this Caucasian lady at work and she noticed i was pregnant we held a conversation for a really long time. And she said she wanted to help me out with baby stuff so we exchange numbers and she said she’s going to give me all of her grand baby stuff that he can’t wear anymore. So we texted after she left she’s 40 and I’m 20 and we had a really nice conversation so i told my friend about the nice lady and my friend was all judgmental and was like have you not seen lifetime movies when white women are crazy and they try to take people babies and hold them hostage and I’m like ummm but she seem really sweet. So i told my fiancé and he said the same thing. Now I’m upset because they’re going all crazy and dramatic because i actually like this lady and think she’s sweet 🤷🏽‍♀️ she even said if i ever needed a place to stay that i could come to her and she didn’t mind helping me out. They think because I’m black she’s out to get me because she’s to nice 😡 which i don’t think is true. Anyone have any opinions???
